We examine how the information produced by analysts when they initiate coverage contributes to the mix of firm-specific, industry-, and market-wide information available about the firm. We hypothesize that the first analyst to initiate coverage provides low cost market and industry information allowing him/her to follow more stocks, whereas subsequent analysts provide firm-specific information to distinguish themselves from existing analysts. We use stock return synchronicity to measure the mix of information available about a firm, with higher synchronicity indicating more industry and market information. Coverage initiations of firms with no prior analyst coverage increase synchronicity suggesting that analysts produce industry- and market-wide information. In contrast, analysts initiating coverage on firms with existing coverage appear to focus on producing firm-specific information as these initiations lead to reduced synchronicity. Together, our findings indicate that the type of information analysts produce at initiation depends on the information provided by other analysts.
